Computer Number System problems chapter 5 Part 2 Video Lecture | Crash Course for SSC CGL (Hindi)

hello friends welcome to current affairs
today I am going to complete my second
part of conversion of Nova system before
restarting I want to say something about
my channel
we delivering free education for you so
please spread the word among your
friends and share for those people who
cannot afford coaching and you know
learning is priceless so please do at
least and if you want any specific topic
video then please do comment on our
Facebook channel which is facebook.com
Current Affair funda CEF so friends in
the previous part what we learnt we
learn how to convert any decimal number
into another base now if you got any
fractional decimal number then how to
convert it into in other ways today we
are going to solve this tie kind of
question the procedure is same the part
which is come before fraction will be
treated just like exactly same which we
did in the previous section so we want
to convert 79.1 6 into binary which is
base 2 so divide 79 by 2 so so friends
what will be the question 39 what will
be the remainder 1 divided it again what
will be the question 19 remainder 1
divided it again what will be the
question 9 remainder 1 would we be the
question 4 remainder 1 what will be the
quotient 2 remainder 0
what will be the question one and
remainder will be zero write it wrong
move to toe which is 1 0 0 1 1 1 1 1 now
the question arises how to convert point
16 so we need to multiply it by 2 the
ways in which you want to convert it
which is space 2 so we will multiply
point 1 6 by 2 the answer will be 0.38
extract tough part which is come before
fraction now again multiply 0.32 what
will be gaza 0.64 extracted now again
multiplied by 2 what will be the answer
one point two eight extracted now
multiply it by two what will be the
answer
0.56 our friends this is your first time
to convert any fractional decimal number
into another base so I am doing it to
five time otherwise it is enough to
convert it the fractional part in three
times then stop it
but now this is your first time then I
am going to multiply it if a turn there
was stopped after multiplying it by
three times okay now again multiply 0.56
into two then answer will be 1 point 1 2
stop
right down on extracted digits from top
to bottom so the other will be zero
sorry
unser will be zero zero one zero one
stop it now we need to convert it again
to octa how to do it simple multiply
seventy eight by eight what will be the
question 9 what will be the remainders
seven again multiply it what will be the
question 1 what will be the remainder 1
write it from bottom to top which is 1 1
7 now multiply 16 by 8 what will be the
answer one point two eight extract one
now multiply it again by eight what will
be the other two point two four extract
to now multiply 8 by 8 what will be the
answer one point nine to write it from
top to bottom which is 1 2 1 is 8 now
convert it into hexadecimal for this we
with divide 79 by 16 what will be the
question 4 what will be the sorry what
will be the remainder 5/5 or 15
and in hexadecimal 15 right leg up F so
I get it here from bottom to top
now multiply 0.16 into 16 would will be
the aza 256 now multiply it by 16 what
will be the answer eight point nine six
extracted now multiply 8 by 16 what will
be the answer of fifteen point three six
but 15 is F and out it right it from top
to bottom so answer a bit to e F stop it
now convert 79 into base for again
multiply it so what will be the question
19 what will be the remainder 3 again
divided question will be for remainder
will be 3 again divide question will be
1 remainder is 0 now write it from
bottom to top which is 4 0 3 3 point now
multiply point 16 for what will be the
so if you divide so if you multiply is
0.16 into 4 zero point six or extract
zero now multiply it by four
or again what will be the answer two
point five six cane extract it
multiplier for what will be the answer
to find two for extracted now write that
structured part from top to bottom verb
will be NASA 0.3 0.0 to 2 is 4 so Frank
now we learn that how to convert any
fractional decimal number to another is
next proceeded to over and apart if you
have any sectional number which have
another ways like two eight and five and
you need to convert it into decimal then
how will you do it very simple how will
you do it you just need to multiply each
and every number first of all we are
going to solve this binary fractional
value number into decimal you need to
multiply each 2 Z by 2 but the power
will be two very how I will tell you
first write down like this 0 into 2 1
into 2 0 into 2 1 into 2 divided into
two part first is before fraction and
second is after fraction here the power
of one will go from left sorry yes right
to left again either here after fraction
what will be a procedure here power
will grow from left to right so here our
first father will be zero next check
power of 2 is 1 next power of 2 is 2 now
we curve here the part which is come
after flexion here the power will be
minus 1
power will be minus 2 and power will be
minus 3 solve it what will be the answer
4 plus 2 plus 0 plus 1 by 2 plus 0 plus
1 by 8 now solve it what is 4 plus 2 6
what is 1 by 2 0.5 and what is sorry
what is 0 or 1 by 8 0.125 so the answer
will be plus it all three numbers which
is 6 point 6 2 5 this will be de also so
as there will be six point six two five
now friends we need to convert this
fractional octal number into Jai Simha
the procedure will be same here
each is it divided so if multiplied by H
and the power will increase or decrease
according to their rule so first
multiply each digit by 8 here power will
be 0 1 2 and after fraction 5 into 8 4
into 8 powerful u minus 1 power will be
-2 solve it 64 plus 16 plus 7 plus 5 by
8 plus 4 by 64 what is next
87 plus zero point 6 2 5 plus 0.0625 so
what will be the answer there will be a
t seven point six eight seven five and I
get again you also will be 87
Oh point six 875 base Chan now you need
to convert this number which are phase
five into decimal number so multiply
each device by five zero into 5 4 into 5
power will be zero one and two or after
flexion how it will be multiplied zero
into 5 minus one plus 4 into 5 minus 2 3
into 25 is equal to 75 whatever the
number is multiplied by 0 will be 0 4
into 1 4 plus whatever the number is
multiplied by 0 0 and this will be 4 y
25 what will be the next step 79 plus
0.16 so alsa will be seventy nine point
one six base 10 so people things now we
learn how to convert any fractional
numbers which has another base 2 into
decimal number next conversion we will
not here we will convert a number of
another base to a decimal number
okay this is the last question how you
will date you already done it so let's
start here we have a question 126 so
multiply each digit y 8 sorry plus 2
into 8 plus 6 into 8 and multiplied will
grease the power would we be the answer
64 plus 2 into it
16 plus 6 and the answer will be 86
piece 10 I think I solve many question
to give you a brief knowledge how to
convert funny how to convert into
into another SOI decimal number please
try to convert these to number this is
your assignment to convert into decimal
number I am going to give you the answer
of these two question first question
answer will be 30 base 10 and the second
question also will be 28 6 1 try to
solve it yourself it will increase your
confidence to convert any number into
another base so please friends try to
solve it to yourself if you find any
problem by solving in then please to
comment on my video then I will show you
the step and if any of my friend solve
it first then my humble request to you
friends who did it first
please side down in comment then how do
you solve it please write down all the
steps to another other half your Curry's
other your friends can also see then how
you solved it ok so rest of law for this
do these two question next move to our
another conversion here we will converts
of some base to a number of another base
means if you have a base of another base
and you need to convert it into another
base here there is no base of decimal in
left hand side and right hand side your
base are both side and both side is
different then how to solve it we have
to step first is convert the original
number to a decimal number and then
convert the decimal number to another
base because you know this these 2 way
to convert any decimal number into in
other ways or any another ways to into
decimal so these two step while your by
using this 2 step you can convert very
easy to a number from
other ways to convert it into another
base how solve it let's do it
sorry here we have a question we have we
have a number which have basis six
it is not decimal number and we need to
convert it into base for this is also
not a decimal number then how will you
do it first you know how to convert any
other base number into decimal number
then please solve it how you will do it
to convert any base to decimal number we
need to multiply eight digit by that
base power 4 into 6 5 into 6 0 1 and 2
what will be the next step 5
into 36 + 4 into 6 + 5 into 1 would will
be the next step 180 plus 24 plus 5 is
equal to 2 0 9 base 10 so our first step
is calculate which is convert the
original number to a decimal number
which is this can be converted now we
will follow the second yet step here we
convert this decimal number to the new
piece and you know how to convert any
decimal number into new base de vie
2:09 by
for we need to convert it into Warner so
we divide it 2:09 by 4 what is it with a
question 52 Amanda will be one wood will
be the question 13 remainder will be 0
woods will be the remainder the vendor
will be 3 and so equation will be 3 and
remainder will be 1 now write it from
bottom to top so your answer will be
what will be our answer your answer will
be 3 1 0 1 simple
formed using this method you can convert
any number which have another base to a
number which are another base now we
will move to our another conversion here
we will learn the shortcut method for
converting a binary number 2 is
equivalent optimum how to convert any
binary number to its equivalent octal
number look if you follow the convention
method like if you have a binary number
1 1 0 so how you be converted into octal
you will convert it into octa by
multiplying it first two then you will
get a decimal number
then you will convert that decimal
number into octal number by dividing it
by a this is a very large process so we
have a shortcut method how to do it this
is the way divided that each digit into
group of 3 is starting from right how we
will learn this step by using question
now we got the pusher we got the
question which is 1 1 0 1 0 1 0
first step what is saying divide the
desert into groups we need to divide
visit into groups of three starting from
right so start from right and divide
each digit into group of three this is
first row this is three one is left
alone so we write zero and here
automatically okay
so write it like this one one zero one
zero one zero this is the three group 0
0 now convert it into simpler way
decimal number or how to do it to
multiply it by 2 to 2 power to the power
0 to the above of 1 to the power 2 here
these two numbers are 0 so whatever we
multiply 8 by 2 will give you answer to
so we have only this one one left
and we will divide it by 2 to the power
1 so answer will be 2 exactly like this
you will do these questions what will be
the answer 5 and this will be 1 so keep
practice only then you will learn how
this will come otherwise you will follow
the conventional method simple this will
come up to 1 4 2 1 4 2 1 & 4 & add all
those nava in the group which have one
here we this number is have 1 then write
it to these two number have 1 4 plus
sorry 1
sorry friends here again sorry
one two one two
so here these two numbers have one plus
it 4 plus 1 5 1 1 5 2 and this is the
awesome this is a shortcut way next we
proceed over another color conversion
shortcut method of converting your octal
number to its equivalent binary number
how to do it here you got the pusher for
what is your fastest a convert each
octet is it each means five six to each
octet is it two or three is it Barney
number the operators may be started up
jessamine for this conversion you can do
to convert five into binary six into
binary 2 into binary by using
conventional method or just learn like
five write like this it will be 1 0 1 6
will be right like this 1 1 0 & 2 will
be 2 1 0 and write it it combinely 1 0 1
1 1 0 0 1 0 this is the shortcut way to
convert your octal number into binary
number now force it over next conversion
which is the again shortcut method for
converting a binary number to its
equivalent hexadecimal so the stuff will
be same but there is a question which we
have evolved to convert it into a
hexadecimal number in the previous
question we convert the binary mine to
octal number
so we what to do it for sister divide
binary digits into group of four is
starting from the right how to do it
let's do it here you have a question 1 1
1 1 0 1 what is your first step saying
divide the binary digit into group of 4
starting from the right so divine T is
number into 4 groups
zeros I have 2 digit as missing so we'll
write it 0 0 because whatever we
multiply by 0 you will give you also 0
so know how so here write 0 0 extra true
can convert this group into food and
please convert it into decimal number
what it will be 1 2 4 8 1 2 4 8 and add
those number who have one here 8 4 and
1/2 1 so the answer will be 13 and here
also will be the three but 31313 how we
write 13 here we will write 13 as a is
tan B is 11 C is 12 and D a 13 so we
write it it 3 so the answer will be 3t
power sorry this 16 now move to our
another conversion here with we will
find how the sort shortcut matter to
convert a octal number 2 is equivalent
value number sorry it is not an octal
number it is a hexadecimal number what
is hexa decimal number what is false
Church
do it by using question convert the
decimal number equivalent of each
hexadecimal digit to a 4-0 binary number
here - how will be the - right into the
binary 0 0 1 0 a a what is if a is 10 so
10 will be right like 1 0 1 0 and B 43 B
is 11 so 1 0 1 1 right these number
combinely 0 0 1 0 1 0 1 0 1 0 1 1 this
is the way to convert any hexadecimal
number to its equivalent minor e number
now we have done overall conversion
please trying to do this quotient by
yourself first write down it like with
whatever I do it then please practice it
using more and more number and think how
it will turn if you want practice then
all the conversion method will be will
have no use for you so please things try
to do it yourself find out some
questions from your books or some net
and do it otherwise I am going to give
you a mcq very shortly where we will
solve number systems cautious I will
give you some 30 to 20 20 to 30
questions there
and where we will solve those those
question and you people also try to
solve it very soon the dot and that one
video also is going to come so please
till then try to solve
this matter using these numbers and keep
practicing and please people subscribe /
